You won’t be afraid if you learn mathematics, physics and chemistry well and cultivate immortality

Yizhou, the last barrier of the Daqian capital, has become a majestic and magnificent city after thousands of years of repairs. The city has high walls and thick walls, numerous archery towers, and complete city defense facilities. It is like an indestructible iron wall and copper wall.

The city wall is tall and strong, like huge stone mountains rising from the ground, tightly surrounding the entire city. The city walls are densely covered with arrow towers, standing proudly like towering trees in the forest. On the archery tower, the archers stood ready and watched all movements outside the city vigilantly. They carry long hardwood bows on their backs. As long as there is a war, they can draw their bows and shoot arrows at the command, and dense arrows will fall like raindrops. They are all stationed on the towers, ready to deal with the enemy's attack at any time.

The width of the city wall is more than ten feet, and it is okay to let the cavalry roam freely on it. After all, the cavalry are strong soldiers in the army. When mounted, they can bend bows and arrows and gallop on the battlefield. When dismounted, they can also wear armor and charge into battle. In case of emergency, If there is a gap in the city defense, these elite cavalry can provide support at any time.

The roads in the city have been renovated to be wide and clean, with a standard width of ten feet, making it easier to rush to the city gate for defense. The buildings on both sides are well-proportioned, showing a prosperous scene. There are all kinds of shops, restaurants, inns and other places, and the vendors are also bustling. The haze of war does not affect the excitement and bustle of Yizhou City at all. However, behind this prosperity is the result of months of hard work by the third prince.

The third prince, who fled hastily back from the battlefield, knew the importance of Yizhou. This time he personally directed the construction of the city defense. He persuaded the family members from the aristocratic families and military generals' families who supported him to pool their wisdom, find out and fill in the gaps, and make Yizhou a better place. The state's defenses were more difficult to overcome. Not only did he add a lookout tower on the city wall to detect the enemy's movements in time, he also set up numerous mechanisms at the city gate to prevent enemies from sneaking into the city. He also recruited civilians to dig wide and deep moats at the corners of the city, which is expected to increase the difficulty of attacking the city. several times. Anyway, we can't defeat the superior troops in a plain battle, so let's defend the city! According to the military book, if you want to capture a city, the strength of the attacking and defending sides must be at least three to one. That means there are 100,000 soldiers stationed at the top of the city. To capture the city, you need about 300,000 troops, not to mention the benefits. There are hundreds of thousands of people in the city.

In addition, the third prince also strengthened the training and equipment supply of the army. This time he personally selected elite soldiers, formed a strong garrison, and gave them the best treatment and rations. The soldiers wear the strongest armor, hold sharp swords, are well-trained, and have extremely strong combat effectiveness. A large number of advanced weapons blueprints were also collected from these military families and assigned to the craftsmen of the Ministry of Industry to build ballistas, trebuchets, etc., giving Yizhou more advantages in offensive and defensive warfare.

After the painstaking efforts of the third prince, Yizhou's city defense facilities have reached their peak, and it has been built into an indestructible military city. Whether it is the height of the city wall, the number of arrow towers, or the quality of the defenders, weapons and equipment, it can be said that First class. This made Yizhou the last barrier to the capital of Daqian. On the day of completion, the representatives of the aristocratic families and the children of the military generals' families all expressed high praise and affirmation of the third prince's ability. Standing on the towering city wall and looking around, overflowing with joy With murderous weapons and well-equipped soldiers, they all believe that if they want to break this city, they will pay a heavy price.

As for the reconstruction of Yizhou City, Jun Yimo also knew the news very well through the spies. Unfortunately, his strength did not allow it. Although our side won the decisive battle in Cailu Plain last time, it was a tragic victory with the loss of troops and generals. Even if it gained a lot from gathering war resources after the war, Feng, but the elite soldiers have been damaged, so they can only continue to recruit new soldiers, transfer and promote soldiers with outstanding military achievements in the previous war, and lead some veterans to form a new regiment to train together.

Of course, the generals headed by Commander Lian Po were also summoned to analyze how to break the offensive and defensive battle of Yizhou Fort. Judging from the known information, no matter how you analyze it, there is no solution, and manpower is exhausted, unless you can invite high-level immortal cultivators to avoid the big killer weapons on the city walls and suddenly take action, using magic weapons and great supernatural powers to directly attack Lowering it to ten levels will increase the probability of successfully breaking the game. However, these monks on the mountain have an unwritten rule in the world of immortality. These people are not allowed to interfere with the change of secular dynasties. Otherwise, they will end up with the fate of life and death. It is impossible to secretly take action in such a large battle. It's possible, after all, this offensive and defensive battle also attracted many immortal cultivators on the mountain to watch, overtly and covertly. Some monks also started betting on the outcome. Small gambling is a kind of spiritual practice. Just like the decisive battle on the Cailu Plain, it was on a scale unprecedented in human history for thousands of years.

The scale of Jun Yimo's review of the three armies this time was also unprecedented. The 100,000-sized military formation was silent, and a chilling air came to his face.

The main siege equipment used in this siege battle also appeared one after another. The first thing that caught the eye was the behemoth-like trebuchet lying across the back of the school ground. The crossbows sent from the blacksmith shop were laid out at the front of the school ground. The huge arrow with the thickness of an arm shone with cold light, and as long as the operator knocked down the firing mechanism, it would shoot a big hole in any obstacle in front of the arrow. These bed crossbows are specially made. For this reason, Iron Hammer went to Cangmang Ridge to kill several huge low-level monsters. They skinned, cramped, and pulled out the bones to use them to make this bed crossbow and trebuchet. Their flesh and blood were edible. Nothing is wasted. The range of this specially made bed crossbow is almost double that of the one carefully crafted by the Ministry of Industry, and its power is more than double. According to personal test data, an arrow made of fine iron can hit a boulder at a distance of about five hundred steps and can penetrate the stone. Of course, for such a powerful weapon, the accuracy is very impressive.

The two movable towers in the middle are also very eye-catching. They are like moving fortresses. The tops of the towers are not only covered with low-level monster skins that are invulnerable to weapons, water and fire, but also have rails for shooting crossbows. For any target in front of the tower, there are also many shooting holes reserved for sharpshooters to shoot arrows, which can easily kill the enemies within sight within the shooting range.

There is a ram cart lined up under the tower, which has no other function than transporting troops and breaking open the city gate.

As for whether there are other secret siege equipment, it is unknown.

This time there were several times more troops than in Cailu Plain. They were not just siege soldiers, but also various special forces. Hundreds of people passed by the square pushing behemoth-like siege equipment. It was also very shocking. Fortunately, these siege machines all use bearings to push them more effortlessly. Otherwise, it would take thousands of people to move such a large machine.

Commander Lian Po gave the order, and after Her Majesty the Queen Jun Yimo reviewed the troops, the engineering troops began to disassemble the main components and transport them to the designated location through a pack truck specially designed to transport equipment.

When a hundred thousand troops set off for the expedition, there was a continuous flow of flags, especially the team responsible for transporting the siege equipment, which stretched for more than ten miles, and the civilians who followed behind to transport grain, grass and heavy supplies could not see the end from the beginning.

The war lasted for three months, and the siege battle with family letters worth ten thousand gold could start in less than a month. The third prince had already received general information about the siege team. In terms of numbers and strength, they were almost the same. If the government soldiers were included, they would definitely have the advantage. , let alone a city defense battle, these people must have the strength to lift rolling wooden rocks and smash them down! In this case, he didn't even bother to do small things such as attacking and killing the vanguard or intercepting and burning food and grass. He only made one decision, to reward the three armies, eat and drink enough, and recharge his batteries to wait for another battle with Commander Lian Po. This time he wanted to avenge his shame and become famous in one battle. Last time when he had a big advantage, he only sent out his own direct lineage to join forces with Lao Ba because he was afraid of losing the credit. He didn't expect to lose so miserably, so this time he brought all the elite dead soldiers raised by the mother clan's forces.

Everything is unknown, so just wait quietly.

Without any ups and downs, the army set out and marched for about twenty days. The vanguard finally arrived ten miles away from Yizhou City, where they set up camp and waited for the arrival of follow-up troops, food, baggage, and siege equipment.

Although we had roughly understood the layout of Yizhou city defense based on the secret report, the sentry responsible for inquiring about the military situation did not know until he got close to the distance and took a closer look that the majesty of Yicheng cannot be expressed and described in words. Talk about the defensive facilities on the city wall and the moat that is like a big river. Just look at the Juma Zhuang in the open space outside Yizhou City. If you have trypophobia, your scalp will go numb just by looking at it. In addition to a necessary road reserved for two carriages, within a hundred steps of the city wall, there are horse-proof stakes buried deep in the ground everywhere. This was the case when riding a horse and running around the city. The defense map on the city wall was also marked and corroborated with the intelligence obtained. It was found that there were more weapons than what was stated in the intelligence. When the vanguard of Commander Lian Po arrived outside the battlefield, At that time, the third prince sent more defenders to the city wall to strictly defend it. He knew that the other side must already know all his layout and plans, just as he already knew the general situation of the siege troops led by Commander Lian Po.

Three days later, the subsequent large forces arrived at the camp ten miles away. After waiting for another two days, the siege equipment was also transported up by the civilian workers who worked day and night and worked tirelessly.

Then, after the military staff sand table war attack and defense simulation at the Military and Political College, Commander Lian Po gave the final word on the military order. Instead of spreading out the troops and trying to attack in vain, it is better to concentrate all the forces on a frontal attack.

In this case, let’s arrange our troops! No matter how you attack, you must first remove the horse-repelling stakes buried deep in the ground. Otherwise, if the team formation is disrupted, your casualties will immediately increase several times, and even affect the morale of the entire legion.

We have already prepared to deal with this kind of horse-rejecting pile. At first, we wrap it with iron chains and use the mobility of the horses to drag them out together. We can also send sword and shield soldiers with giant axes to risk their lives to remove the obstacles. Of course, the old commander Lian Po However, he was well-read in military studies and experienced in battles. He received secret black technology equipment from the blacksmith shop, five flamethrowers. To put it bluntly, they are similar to the dust explosion during iron-making in a blast furnace. Here, coal powder is used to manually The bellows burned, and a large amount of fine charcoal powder was added from the side, and then an explosion-like temperature was generated in an instant. It spurted forward through the pipe and burned directly on the wooden horse pile a few steps away, igniting it. Of course, the protective measures of this equipment are also very in place. Its biggest advantage is that it cannot be penetrated by the city head crossbow. Although the movement is slow, the effect is very powerful. Slowly, it is easy to pull out those horse-repelling stakes without hurting any soldiers.

The powerful trebuchets and bed crossbows on the city tower all relied on luck for their accuracy, so they all used their strength to focus the fire for several waves. Even if it was shot into a giant hedgehog, it did not affect its ability to continue burning without any scruples.

The most important thing is time and patience. After a day, the horse-rejecting stakes are slowly removed, and then the siege officially begins.

The first to appear were the powerful bed crossbows and the reassembled towers. When they were about five hundred steps away from the city wall, they all stopped and started loading arrows to shoot. The giant arrow as thick as an arm was nailed into the distant city wall with a sound of breaking through the air, the sound of the collision of gold and stone, and the trembling sound of the giant arrow exposed outside the stone wall. Each time is exciting. The most shocking thing is that an arrow missed the target and directly hit the crenellation on the city wall. The power of the giant arrow not only collapsed the small crenellation, but also caused the debris to fly around, causing countless defenders to lose their weight. A record of casualties.

Fortunately, the number of these crossbows was limited, and they fired more than ten rounds in succession. From a distance, it looked like the entire city wall was densely packed like hedgehogs.

Commander Lian Po felt that it was not enough at first glance, so he ordered his men to fire volleys for ten more rounds before he felt that it was almost enough.

Next, the trebuchets and trench crossing vehicles should come on stage.

The random falling points of the trebuchet are very touching. Fortunately, it is good to be able to roughly control the throwing of rocks on the top of the city. Of course, the trebuchets and crossbows on the top of the city are not to be outdone. They happen to be able to fight back with their height advantage. This Not only did the two sides fight back and forth, but from time to time there was a wailing sound from the city wall. Those outside the city who were accidentally shot by boulders and giant arrows basically died on the spot. Those who were attacked by these big weapons and survived by luck. Either a few ribs were broken or bones of hands and feet were broken, and he was in a state of life worse than death.

War is so cruel, what can be done? When the moat truck arrived in front of the moat despite the damage and began to set up logs and lay planks forward, the defenders on the city wall, under the command of the third prince, held the flying rocks on their heads and started shooting arrows downwards, wave after wave. The arrows rained down, and the trench-filling soldiers who showed flaws would be hit by arrows. If they were lucky, they could escape with their leather armor. If they were close, there would be no chance. Now during the war, there was no chance to collect the corpses. Trench-crossing vehicles Transport the trench filling materials back and forth to lay the pontoon bridge. The people on the city wall will make it so easy for you. Rolling logs dipped in kerosene and bundles of ignited wood are dropped from the city head, trying to build bridges that have not yet been completely set up. The bridge is burned down here. How can the old commander Lian Po let you succeed? He ordered people to transport baskets of soil to cover it.

There is a saying in the Art of War that this kind of moat can be filled with earth and rocks. Even if it is a moat, it is still a river. Its width and depth are not ordinary small ditches and canals that can be covered by just adding earth and rocks, even if enough water is poured into it. The earth and rocks will eventually turn into a quagmire similar to a swamp.

After a day and a night of non-stop back and forth, both sides suffered thousands of casualties, but a row of pontoon bridges was still built on the moat of this city wall.

It happened to be that the sun was setting, and it was a fait accompli. Both sides had a tacit agreement to withdraw their troops and not attack each other, recharging their strength and waiting for tomorrow's bloody battle.
